configure: error: leptonica library missing (when building tesseract-ocr-3.01 on MinGW)

Question

When running configure it fails with

checking for leptonica... yes
checking for pixCreate in -llept... no
configure: error: leptonica library missing

But I have leptonica 1.69 built (downloaded source and ran ./configure && make install)

---

Edit

I think configure: error: leptonica library missing is a bit misleading, please note that it first says checking for leptonica... yes, and then fails on checking for pixCreate in -llept... no. So maybe the problem is not that the library is missing, but something else.

Answer 1

I am working on redhat linux 7.2 . None of the solution worked for me
I was getting following errors in config.log.
Package lept was not found in the pkg-config search path. Perhaps you should add the directory containing `lept.pc' to the PKG_CONFIG_PATH environment variable

PKG_CONFIG_PATH
configure script uses pkg-config utility to check for packages .
It was not able to find lept package ( although i had installed leptonica seperately )
By setting PKG_CONFIG_PATH pointing to the directory where lept.pc is present , i was able to resolve the issue .
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
